In order to keep correct informations about labels in MapInfo WOR files, is it possible to keep blank lines in MapInfo Tab file after tranformation?

The problem is that WOR files keep coordinates of labels who have been placed manually.

The object number refers to the ROWID (rank in the table), unfortunately not to object ID. If blank lines are deleted after compacting table, those object numbers refer to wrong object.

So is there a way in FME to keep those blank lines after transformation?

Thanks :-)

Hi @ecvitznau, if the reader reads the blank features from the source MITAB file, you can write the transformed features and those blank features into the destination MITAB file in the same order as the source. e.g.

  1. Counter: Add an attribute (e.g. "_count") storing sequential number to every feature including blank ones.
  2. Tester: Separate the feature flow into non-blank features which should be transformed and the blank features by an appropriate test clause.
  3. Transform the non-blank features, and keep the blank features as-is. DO NOT discard the blank features.
  4. Send all the transformed features and the blank features to a Sorter and sort them by the "_count" to restore the original order. Then write them into the destination MITAB file.
